Question

The entrance ticket for a carnival costs $89.97, which includes a royal meal that costs $10.85, 1 play station game, and 3 water rides (Each water ride costs the same price). The cost of a water ride is twice as that of a play station game. Find the cost of a water ride. Estimate to the nearest tenths.

$18.70
$21.40
$22.60
$24.40

Answer 1

`\huge\boxed{\sf Water\ ride = \$22.60}`

Explanation:

Let the cost of play station be x.

This will make the cost of water rides to be 2x (twice).

Given condition:

Entrance ticket = Royal meal + 1 play station + 3 water rides

So,

89.97 = 10.85 + 1(x) + 3(2x)

89.97 = 10.85 + x + 6x

• Subtract 10.85 from both sides

89.97 - 10.85 = x + 6x

79.12 = 7x

• Divide both sides by 7

79.12/7 = x

11.20 = x

x ≈ 11.20

So,

Play station game = $11.20

Since the cost of water rides is twice, so:

Water ride = 2 × 11.20

Water ride = $22.60
